Sections 3 of each corner post or upright are arranged in longitudinal alignment with each other with their ends abutting and at the abutting portions of adjacent sections of each corner post, there is provided what I term an angular splice bar unit (S, for connecting the adjacent ends of the superjacent sections of the respective corner posts together.

Attention isV now directed to Figures 6 and 7 of the drawings, wherein there is 'disclosed the specific construction of one of said splice bar units. A relatively large angular bracket 7 is secured against the outer face of the upper end portion of each section 3 and it will be observed that the side edges of the angular plate or bracket projects beyond the adjacent side edges of the angle iron sections,

- while the upper edges of the angular plate project above the upper edge of said section, and suitable notches 8-eXtend downwardly from the upper edges of the sides of the angular bracket or plate 7 and terminate at a point above the upper' edges of the respective sides of the section 3, for a purpose to be presently described.

Angularly disposed slots 9 are formed in the upper corner portion of the angular bracket or plate 7 while secured to the outer face of each side of the angular plate or bracket are the fiat strips 10, the same being spaced from the respective sides of the angular plate or bracket through the medium of spaced washers 11 that encircle the fastening rivets 12, and the purpose of this particular arrangement for construction will also be presently described.

A smaller angular bracket or plate 13 is secured on the inner face of the upper end portion of each section 3 in such a manner that the upper portion of this inner angular plate 13 projects above the Lipper edge of the section 3 as shown very clearly in Figures 7 and 8 of the drawings. Rivets or the like are employed for securing the inner and outer plates to the upper end of each angular section, and certain of these rivets denoted by the reference character 111 have their outer threaded ends spaced from the outer faces of the angular bracket or plate 7, by suitable spacing sleeves, shown at 15, for a purpose also to be hereinafter more fully described. Relatively thin spacing members 19 are interposed between the inner angular' brackets or plates 13 and t-he adjacent sides of the up per end portion of each section 3.

An angular metallic bracket 1G is secured on the outer face of the lower end portion of each section 3 and as is clearly shown in Figure 6, the lower edge of each side of the angular bracket 16 is directed to provide a laterally disposed foot 17. The inner corners of the laterally disposed feet are cut away illustrated at 1S.

Suitable spacing elements are associated with the fastening rivets 2O to maintain the lower angular bracket 16 in spaced relation with respect to the outer face of the respective sidesof the lower end portion of each section of each corner post or upright.

The invention further comprehends the provision of a particular girt construction for association with each pair of adjacent corner posts, and in Figures 4: and 5 of the drawings, there is shown in detail, the specific construction of one of the girts. The girt is formed of angle iron material and is designated by the reference character 21. These girts extend horizontally across thel outer faces of each pair of opposed angle brackets 7. The vertical wall or side of each angle iron disc is formed at one end with the cut-away portion 23 and inwardly of this cut-away portion the vertical wall 22 of each girt 21 is formed with a slightly inclined notch 24, whereby to provide a finger 25, that is disposed between the spacing elements that encircle the rivets 12, it being understood that the vertical walls 22 of the angular girt 21 is disposed between the outer face of the angular bracket 27 and the adjacent,strip 10, as is shown very clearly in the detail in Figure 12.

The other end of the vertical wall 22 of each girt is also cut away as at 26, and a notch 27 is formed at a point inwardly of the eutaway portion 27, whereby a linger 23 is formed between the cut-out portion 26 and the notch 27. The only difference between the linger 28 and the linger 25 is that the finger has both of its side edges disposed at an incline whereas the linger 28 has only one edge disposed at an incline, and this particular edge forms one side of the notch 27 The girts 21 are positioned horizontally across the sections of the adjacent corner posts and are installed subsequent to the erection of each series of sections.

In the erection of the derrick, the lowermost sections are initially secured to the channel bars 5 of the base 4, whereupon the lower ends of the superjacent sections lit between the spaced inner and outer angular plates 13 and 7 respectively, the notches 8 acits() lli Vin Figure 5.

commodating fthe fastening ,elements 20, whilethe lower edge of the'superjacent sections willrest `upon the upper `edge of Vthe neirtlower section asy indicated very clearly in Figure 8.

Prior to the arrangement of the upper 4sections upon ythe lower sections, the girts are placed in position and initially the girts are disposed in the manner as shown in Figure 5, whereinithe linger 25 is positioned between the spaced fastening elements 10, while the other end of each girt assumes the position shown in Figure 5. It is necessary to employ a special tool for properly positioning the girt across the opposed pairs of spliced bar units and this tool is shown generally at 29 The tool is specically described in aV co-pending application and therefore a detailed description of the same in the present instance is believed unnecessar t will, however, be observed that this tool is adapted to engage one end of the horizontal side of the girt, while another portion of the girt engages with the inner end of one of the fastening elements and by manipulating the lever 30 of the tool, a downward pressure is exerted on the right hand end portion of each girt to properly position the finger 23 between the adjacent fastening elements 10, as shown in Figure 4, and when the girt is thus positioned, the upper ends of the assembled sections will be maintained in a rigid manner for receiving the superjacent l sections and the laterally disposed feet 17 will engagev with the upper face of the horizontal portion of the respective girts to properly secure the same against upward movement.

For the purpose of further securing the assembled parts of the derrick in a rigid manner, I employ the brace rods 31, one of which is Yshown in detail in Figure 14. A relatively small hook 32 is formed on the lower end i of each brace rod for engagement within the respective slot 9, while the upper end of each brace rod is formed with an enlarged hook 33 to engage the diagonally opposed fastening element 14 in the manner as clearly .suggested in Figures 1, 4, and 5 of the drawings. These brace rods are arranged on each side of the derrick. Additional reinforcing means shown generally at 34, is associated with the sections of the corner posts or uprights, and

thelower portionof ,the angular bracket 36 projects .beyond the lower edges .of the re-l spective sidesl o'fthef cap member 35, so as to have abutting engagement with the upper edge of the respective corner posts or uprights as yclearly shown in Figure 9. The

notches 8 formed in the sides of the angular bracket .7 carried by the uppermost sections receive ,the fasteningmeans 37, provided for securing ,the kangular bracket 36 to the`` cap member- The top portion of the cap member 37 is illustrated at 38.

` The topstructure further includes the provision of a pair of opposed headers denoted generally by the 'reference characters 39 and respect to the web portion 43 by arranging spacing elements around the rfastening members 44 that secure the strips 42 to the web portion V43.

Each header unit 39 Yfurther includes the provision of an elongated angle iron bar 45, the horizontal portion of which underlies the bottom flange- 46, of the I beam with the vertical wall of the angle iron bar 45 disposed adjacent the inner edge of the bottom flange 4G.

The fastening yIneans'for the angle iron bar 45is illustrated at 47 and a spacing element 48 is associated .withthe'fastening means in v the manner as clearly shown in Figure 10.

InA Figure 13 there is shown the manner in which the angle iron )bar 45 isassociated with the bottomflange 4G of the I beam header 39. The top portion 33 of thecap member 35 lits between the horizontal wall of the angle iron bar 45 and the bottom face of the flange 46 as suggested very clearly in Figure 9. The top structure further includes the side headers 49, a pair of such members being provided for .disposition ybetween the free ends of the opposedheaders 39.

Each of the headers 49 is of channeled v formation and the bottom side ofeach channelvshaped member is `cut away at its ends as is also the respective ends ofthe base portion^50 so that the upperside of the channel shaped member hasits extremities projecting beyond the ends of the base ,portion to provide an ear 51,'for a purpose to be presently described. l

Secured to opposite sides of thebase portion50; ,of the channel member 49 at each end thereof are .thecomplementary elements 52 .andf53, .thatareso constructed as to provide a. slotted housing for receiving the respective strips 4:2 whereby to provide an interlocking connection between the ends of the headers 49 with the respective ends of the headers 39 and the ears 5l will extend over the upper edges V oi" the uncovered web portion 4:3, formed by the cut-out portions 4l. In this manner, the top structure can be readily and easily assembled or disassembled and when the parts are properly assembled the top structure will be adapted to provide a rigid unit accommodating the drilling mechanism (not shown) in the manner well known in the art.

It will thus be seen from the foregoing description that I have provided a derrick construction that can be quickly assembled and disassembled without putting in or taking out a bolt, and the girts and braces will provide suiiicient means for maintaining the sectional uprights or corner posts in assembled relation. Furthermore, by construction a derriclr in the manner as shown and above described, the same can be formed of any desirable height and after the well has been drilled the derriclr can be dismantled and set up over a new vwell to be drilled.

A derrick structure of the above mentioned character will not only be strong and durable, but can furthermore be constructed at a very low cost, and also the various adjuncts which are commonly associated with a derrick may be attached thereto in any appropriate manner.

Wlhile I have shown the preferred embodiment of my invention, it is to be understood that various changes in the size, shape and arrangement of parts may be resorted to, without departing from the spirit of the invention or the scope of the appended claims.

Having thus described my invention, what I claim as new is:

l. In a derrick, a plurality of superimposed sections forming corner posts, spaced inner and outer angular plate members secured on the upper end of each corner post, the upper portions of said angular plate projecting above the upper end of each corner post, the lower end yof the superjacent section having interiitting relation with the angular plate members, the adjacent edges ofv said superimposed sectionsy having abutting engagement, girts connecting the corner posts of each section together, and means for locking the girts in place, said locking means including an angular `plate secured on the outer face of the lower end of the superjacent section adapted to engage the top of the adjacent girt.

2. In a derriclr, a plurality of superimposed sections orming corner posts, spaced inner and outer angular plate members secured on the upper end of each corner post, the upper portions of said angular plate projecting above the upper end of each corner post, the lower end of the superjacent section having intertting relation with the angular plate members, the adjacent edges of said superimposed sections having abutting engagement, girts connecting the corner posts of each section together, each girt comprising an angle iron member, the vertical sides thereof being cut out and adapted to be disposed between the spaced plates, and elements extending transversely between the spaced plates for cooperation with the cut outA portions of the angle iron girt, and an angular plate secured on the outer face of the lower end of the superjacent section for cooperation with the horizontal side of the adjacent angle iron girt to lock the girt in place.

In testimony whereof I aiiiX my signature.
